Description

The fuze consists of a vane cap, fuze body, and magazine. The vane cap is firmly attached to the vane cap hub, which is threaded over a hollow projection on the top of the fuze body. Extending down from the center of the hub is a striker-retaining pin, which in the unarmed position, forces the striker downwards against its spring. Two small pins are located 180° apart on the outer edges of the hub. In the unarmed position these pins are engaged in two shallow slots in the setback collar.

The setback collar is a brass sleeve fitting around the vane hub and resting on the inertia spring. On the bottom edge of the collar are four studs, which engage in holes drilled in the top of the fuze body when the fuze is unarmed. The tapered top edge of the setback collar is cut away in two places to form two shallow slots and two deep slots, which are connected by a cut-down portion of the collar.

In the lower portion of the fuze body is located a shuttered detonator. This detonator is held offset in the unarmed position by the point of the striker. A magazine adapter is screwed into the bottom of the fuze body, and a thin metal magazine is screwed into the adapter.

The fuze is fitted with a shipping safety clip (not illustrated), which engages in one of the two drilled holes in the outside of the fuze body and carries a stud which prevents rotation of the arming vanes. The clip is locked in place by a lead seal and is removed manually before the rocket is fired.
